⚠ High-NA Adoption Is Slower Than HopedModerate threat

High-NA is the future of the monopoly, but the future is arriving more slowly than the initial enthusiasm implied, and that lag is a genuine near-term disappointment. ASML's biggest customers have largely refrained from designing High-NA into their current technology roadmaps, finding that today's Low-NA EUV can be pushed further than expected — through multi-patterning and other techniques — and that High-NA's staggering cost and complexity make them cautious. Meaningful High-NA volume is now expected no earlier than the 1.4-nanometer node¹, and more likely around 1-nanometer, years away.

This does not threaten the monopoly — ASML is still the only maker of High-NA, and the customers will need it eventually — but it tempers the growth story in two ways. It pushes a chunk of expected revenue further into the future than the bulls once modeled, and it is a reminder that even a monopolist cannot force the pace of adoption: customers upgrade on their own timetable, driven by their own economics, not ASML's product cycle. The next monopoly is secured; the question is only how long the market must wait for it to pay off, and the answer has repeatedly proven to be 'longer than hoped.'
